I suppose the boots that were available for someone like T&D would be completely different than boots you would buy for your 12-14 year old recreational skater though. I am not talking about what was available at the top of brand, but what was generally sold as reasonable beginners boots. My parents definitely did not go for the cheapest; they wanted the boots to last for a while (and they did last! )Posted lazily but did say 'fairly unchanged' rather than 'figure skates are unchanged...' etc, wasn't making an absolute statement.
I mentioned heatmoulding & a top of the range pair from 30 years ago, which were a model worn by T&D apparently, rock hard, tough boots were available in '84-'94! (& steps taken since to reduce the break in/ need to have a cobbler on call)
